For over a century, the U.S. military has exposed its service members to toxic substances—from mustard gas in World War I to Agent Orange in Vietnam, depleted uranium in the Gulf War, and burn pits in Iraq and Afghanistan. These exposures often occurred without informed consent or long-term monitoring. While legislation like the PACT Act has acknowledged some of these harms to veterans themselves, little to no action has been taken to understand or address the potential effects on their children and grandchildren. Families across generations have quietly carried on with raising children born with birth defects, rare diseases, cancers, and chronic illnesses that science has yet to trace fully.

The Molly R. Loomis Research for Descendants of Toxic Exposed Veterans Act seeks to fill this critical gap. Introduced in the U.S. Senate in 2024 and reintroduced in 2025, the bill would allocate $15 million in federal funding for independent research into how various military toxin exposures—from Agent Orange and burn pits to solvents and radiation—may impact descendants. The goal is to break through decades of bureaucratic silence and scientific neglect by empowering researchers outside the Department of Veterans Affairs to investigate the transgenerational effects of military-related toxic exposures.

This legislation is personal. Molly Loomis, a former National Park Service climbing ranger and international mountain guide, was born with spina bifida—a condition linked to her father’s exposure to Agent Orange in Vietnam. Her story, like those of countless other children and grandchildren of veterans, underscores a painful legacy that the nation can no longer afford to ignore. The Loomis Act marks a turning point: an opportunity to replace silence with science, and denial with accountability.
